Certificate of Analysis Report
for
NCDQ001 NC Dept Environmental Quality
Client SDG: 470611 GEL Work Order: 470611
The Qualifiers in this report are defined as follows:
* A quality control analyte recovery is outside of specified acceptance criteria
** Analyte is a Tracer compound
** Analyte is a surrogate compound
J Value is estimated
U Analyte was analyzed for, but not detected above the MDL, MDA, MDC or LOD.
X Consult Case Narrative, Data Summary package, or Project Manager concerning this qualifier
Where the analytical method has been performed under NELAP certification, the analysis has met all of the
requirements of the NELAC standard unless qualified on the Certificate of Analysis.
The designation ND, if present, appears in the result column when the analyte concentration is not detected above
the limit as defined in the 'U' qualifier above.
This data report has been prepared and reviewed in accordance with GEL Laboratories LLC
standard operating procedures. Please direct any questions to your Project Manager, Hope Taylor.

Notes:
The Qualifiers in this report are defined as follows:
** Analyte is a surrogate compound
< Result is less than value reported
> Result is greater than value reported
A The TIC is a suspected aldol-condensation product
B The target analyte was detected in the associated blank.
C Analyte has been confirmed by GUMS analysis
D Results are reported from a diluted aliquot of the sample
E Concentration of the target analyte exceeds the instrument calibration range
H Analytical holding time was exceeded
J Value is estimated
JNX Non Calibrated Compound
N Organics --Presumptive evidence based on mass spectral library search to make a tentative identification of the analyte (TIC). Quantitation is based
on nearest internal standard response factor
N Presumptive evidence based on mass spectral library search to make a tentative identification of the analyte (TIC). Quantitation is based on nearest
internal standard response factor
N/A RPD or %Recovery limits do not apply.
N1 See case narrative
ND Analyte concentration is not detected above the detection limit
NJ Consult Case Narrative, Data Summary package, or Project Manager concerning this qualifier
P Organics --The concentrations between the primary and confirmation columns/detectors is >40% different. For HPLC, the difference is >70%.
Q One or more quality control criteria have not been met. Refer to the applicable narrative or DER.
R Sample results are rejected
U Analyte was analyzed for, but not detected above the MDL, MDA, MDC or LOD.
UJ Compound cannot be extracted
X Consult Case Narrative, Data Summary package, or Project Manager concerning this qualifier
Y QC Samples were not spiked with this compound
^ RPD of sample and duplicate evaluated using +/-RL. Concentrations are <5X the RL. Qualifier Not Applicable for Radiochemistry.

N/A indicates that spike recovery limits do not apply when sample concentration exceeds spike conc. by a factor of 4 or more or %RPD not applicable.
^ The Relative Percent Difference (RPD) obtained from the sample duplicate (DUP) is evaluated against the acceptance criteria when the sample is greater than
five times (5X) the contract required detection limit (RL). In cases where either the sample or duplicate value is less than 5X the RL, a control limit of +/- the
RL is used to evaluate the DUP result.
* Indicates that a Quality Control parameter was not within specifications.
For PS, PSD, and SDILT results, the values listed are the measured amounts, not final concentrations.
Where the analytical method has been performed under NELAP certification, the analysis has met all of the
requirements of the NELAC standard unless qualified on the QC Summary.

Data Summary:
All sample data provided in this report met the acceptance criteria specified in the analytical methods and
procedures for initial calibration, continuing calibration, instrument controls and process controls where
applicable, with the following exceptions.
Quality Control (QC) Information
Matrix Spike (MS) Recovery Statement
The MS or MSD (See Below) recovered spiked analytes outside of the established acceptance limits. As similar
recoveries were displayed in the MS and MSD, the failures were attributed to sample matrix interference and the
data were reported.

Data Summary•
All sample data provided in this report met the acceptance criteria specified in the analytical methods and
procedures for initial calibration, continuing calibration, instrument controls and process controls where
applicable, with the following exceptions.
Miscellaneous Information
Additional Comments
Some analytes are X qualified because the standards used to make the initial calibration curve did not meet the
ISO 17025 criterion. These are the only standard available for these analytes. Due to elevated concentrations of
PFAS compounds, the following samples were not extracted but diluted and analyzed only. 1204222797 (MB),
1204222798 (LCS), 1204222799 (LeachateBiotankDUP), 1204222800 (Leachate/Biotank DupDUP),
1204222801 (LeachateBiotankMS), 1204222802 (LeachateBiotank DupMS), 470611006 (Leachate/Biotank)
and 470611007 (LeachateBiotank Dup).
Certification Statement
Where the analytical method has been performed under NELAP certification, the analysis has met all of the
requirements of the NELAC standard unless otherwise noted in the analytical case narrative.
